These members-25 are secured to the clamping member 24 in suitable manner preferably ange 27 through which fas-' by means of a teningscrews 28 pass and engage the clamping member.

Arranged within each tubular member19 is a coil spring 29, one end of which projects through the open upper end of the tubular member 19 and engages the closed end 26 of the member 25. The other end of the spring engages an adjusting screw 30, which is threaded into the lower end of the tubular member 19 and is provided with a knob or handle 31, by means of which thescrewmay be adjusted to vary the tension of the spring 29. a Y Y The normal tendency of the springs 29 is to elevatethe clamping member 24 by their engagement with the closed ends 26 of the tubular members 25, and the height of the member 19 is such that it will not interfere with the clamping operation of the member 24.

The tubular members 25 are connected by means of a web 32 and this web is engaged by a roller 33, carried by an arm 34, the latter being pivotally mounted intermediate spaced uprights 35 as at 36, the free end of the arm v clamping member 24 andis adapted for recip- 1 34 beingpivotally connected as at 37 with the arm 38 intermediate the ends ofthe latter.-

The end 39 of the arm 38 projects over the arm 34Yand is provided-with an adjusting screw-40, which engages the arm 34 for varyingthe position of the arm 38 with respect to j the arm 34 for the purpose of adjusting the clamping member 24=to compensate for vary ing thicknesses of-the covers to be operated The arm 34 is rocked'ab'out its pivot 36 to depress the clamping member 24 against the stress of the springs 29, in any desired or suit able manner butpreferably by means of a cam 41, which is engaged by an anti-friction of the completion of the folding operation,

roller 42 carried by the end of the arm? 38.

This cam 41 is connected with a shaft 43 journaled in suitable bearings '44 mounted upon the base'15, andmotion is imparted to the shaft 43 and the cam 41 in any desired or nected with the shaft.

As soon as this cam passes out of engagement with the roller 42,the stress of the springs 29 'will operate to raise the clamping member 24.

' During the reciprocating movement of the clamping member 24 the latter WlllfllSO be flanges 17, and the walls of this slot are pro- I vided with guide grooves49 (see particularly Figures 5 and 6).

Arranged within the slot 48 is a combined shaper andireenforcing member 50, the body portion of which is provided with laterally pro ecting ears or ribs 51, which reciprocate within the grooves 49. The forward end of,

the member 50 is preferably depressed as at 52 (see particularly Figures 3 and 10) so that v the lower face .of the portion-52 will be disposed so as to be moved into close proximity to theproximate face of the bed 16, and is parallel thereto; "The forward extremity 53 of the portion 52 is rounded so as to conform to the contour of the corner of the book cover while the upper face 54 of the portion 52is conveXed and inclines upwardlyfrom the eX- tremity 53.

Themember 50 is provided with spaced ears 55, between which oneend of a link 56 is pivotally connectedas at 57. The. other end of the link 56 is .pivotally connected with an arm 58, the latter preferably projecting laterally from the link 56 and. is connected with "reciprocating bar or :Ineq'nber 59 moi i ntedf to slide -in'a=su'itable bracket 60.

Owing to the IV-shapeo'fthe recess inthe for- "Waid extreinity'of themembersl e Fi trend)", the margin "of the cover, which has been bent run about the round corner ot the iiljler the member '66, will first be engaged by the memher '81 at two points located one on each side ot the roundcorner of the filler as the member 81 "moves forward to fold the margin.

The member 8 1 is eda pted fora reciproca'ti ngwmovement in a plane transverse "to the plane ofoperation of the flange *69, aind any suitable means may be provided for reciprocating the member 81. It is, however, preferably connected with the shaft 13 to be operated thereby through the medium of a crank arm 84: pivotally connected as at 85 with the cam 41. This arm 8 1 may be of any desired length and the forward end thereof is provided with a socket into which oneextremity of the member 81 projects and is detachably secured to the crank arm 84 by means of a fastening screw 86, so that the member 81 may be interchangedwith another member if desired.

The member 81is so timed in the cycle of operation of the machine that it will not interfere with the operation of the folding member 66 or the operation of the member 50, and each of these members and 66 are also timed so that their operation will not in terfere with the operation of any of the other 'JflltS.

I As the shaft 43 is rotated in the direction indicated by the arrow in Figure 1, the member 81 will be positively moved forwardly and backwardly and when the flange 69 is depressed from the position shown in Figure 3 to allow the turned up portion 80 of the cover to be engaged by the forward end of the member 81, the advancement of this member 81 will depress or further fold the turned up corner 80 into the position shown in Figure 4.

Asa means for holding the end of the member 81 down against the work, a suitable roller 87 is provided which is journaled in suitable bearings 88, and which bearings slide in suitable guideways 89. A spring 90 engages the bearing 88 by one end and the other end of the spring engages an adjustable block or element 91 also movable in the guideways 89. An adjusting screw 92 engages the block or member 91 and through the medium of this screw 92 it will be manifest that the tension of the spring 90 may be varied to vary the pressure of the roller 87 upon the member 81. The member 81 is also supported from beneath and adjacent its forward end by means of a suitable roller 93 journaled in a bearing 94-, which latter is adapted to be raised and lowered by means of an adjusting screw 95. I r

A scraper 96 which is preferably yieldably I supported by means of a spring 97 may be disposed beneath the forward end of the member 81 for scraping therefrom any of the adhesive material suchas glue, paste or the like which might adhere to the member 81.

If desired a scraper 98, controlled by a spring 99 carried by a suitable support 100 may also be provided so as to engage the upper face of the extremity 52 of the member 50 as it is reciprocated, to remove therefrom any adhesive material which might adhere thereto.

plied along the edges of the cover sheet 103,

the sides of the cover are folded over'by hand until they assume the position shown at 105 in Figure 9. That is to say these edges 105 will be sealed down upon the body or filler material 101.

The cover, in the shape as shown in' Figure 9, is then placed into the machine so that the side edges will engage the guides 17 and the corner 102 with the loop shaped portion 80 of the cover 103 formed by the folding over of the sides 105 will project through the opening between the extremities 18 of the flanges 17.,

The first operation is the lowering of'the clamp member 2%. The lower face of the clamp member 2 1is cutaway as at 106 (see particularly Figures 6 and 7) so that when the clamp member engages and rests upon the cover theunsealed portions 80 at the remaining corners 102 of the book cover will not be depressed and sealed down by the clamp member 24, but the cut away portions 106 will stand over those unsealed corners which are beneath the clamp. v

After the clamp has been lowered into contact with the cover the cam 62 will have assumed position to permit the spring 63 to move the member 50rearwardly so that the extremity 53 thereof will pass into or under the looped or folded portions 80 of the cover 103, and the member 50 will move to such an extent that the extremity 53 thereof will co- This member 50 together with the portion 52 thereof will then not only constitute a shaping member but inasmuch as the lower surface thereof is flat and rests fiat against the filler or body portion 101 of the cover it will serve as a re-enforcement for the corner of the filler to prevent injury thereof while the cover 103 is being folded thereover.

'After the extremity 53 of the member 50 has arrived at the limit of its rearward movemeut so that it coincides with the corner 102, the cam 79 will :be brought into operation to engage the roller 78 and depress the member 74 to rock the lever TOV-about its pivot 71 and raise the element- 66 so that its flange 69 will engage the corner portion 80 of the cover 103 see Figure 3 and 10) and to fold this portion upwardly and against the edge of the round h thtcor len, two 891 f0 I F i n 11w l W rk I 012110; and; mfli insvf r'wm t; ahp edt m new -ti0n of theniach in tomo've forw d y e/cam? ;W move ut,
